Abstract

An automatically retractable needle safety syringe apparatus (10) having an integral safety feature that automatically and immediately retracts the piercing tip end (78) of the needle body (16) after a single use, due to a punch (70) which frictionally engages the foundation of the ferrule (84) and a vacuum created within the syringe body (12) during the process of injecting fluid therefore causing the piercing tip end (78) and the needle body (16) to permanently reside enclosed within the syringe body (12) protectively pressed against the inner surface (28) of the tube (18) thus alleviating needle reuse and accidental needle prickings with contaminated syringe needles and therefore ultimately preventing the transmission of blood-borne pathogens and other diseases by contaminated syringe needles. The method of operation is also disclosed.
